What's RTM and I thought the el Diablo was a2
The RTM is Warren DiMartini's signature pickup. It stands for "Rattus-Tonus-Maximus". A take on the Wyle E Coyote and Roadrunner cartoon character descriptions.
It's a slightly hotter JB with an A2 magnet. I need to try one.
correct, and the EL diablo was made for scott ian who wanted a ballsier demon.
magnet is ceramic i beleive
The current El Diablo is NOT related to the Demon in any way, there was supposedly another version at some point, I've never seen it. The current one is the renamed Iommi pickup, and it is not a ceramic magnet, it's what I described above, 2 A2 magnets in 2 Tele Hot Stack bobbins next to each other.

(BTW, he was a complete gentleman about it).
One of the things that makes this pickup unique is that the blades are the actual magnets. So in this sense, it's quite a bit different from the Dimebucker and the rails pickups. Also, the bobbin that's used on this pickup is the same as the STK-S2 Hot Stack for Strat. That means it's quite a bit wider than a traditional humbucker, and it won't fit easily into a traditional mounting ring.
One of the first people to use this pickup after Mr. Iommi, was Mike Tempesta, who was Scott Ian's tech, and then went on to play guitar in Human Waste Project and Powerman 5000. (Nowadays, he's head of artist relations for Yamaha guitars).
There was a Duncan Designed pickup, the HB-104, that also had blades, but it was based on an HB-103 and (IIRC) it used a single ceramic magnet mounted traditionally and the blades were not magnets. It was used by a few Duncan Designed customers, including Schecter in the 5-string Mike Tempesta model.
Nowadays, you can find the pickup, re-dubed as the Scott Ian model, in Scott's new Washburn signature guitar.
And, you can get it from the custom shop as the Scott Ian Signature Model, blade-version. Also, we've tooled up a custom-made mounting ring that fits the wider bobbins.
I hope that helps.

The first is a hotter SH-12 Screamin' Demon. That was the original El Diablo and the name is related to Screamin' Demon. A hotter Demon - El Diablo.
The other El Diablo is the old SH-TI pickup, which was originally created for Tony Iommi, when he was working with Patrick Eggle guitars in the '90s. That pickup went out of production when Tony canceled his SD endorsement to pursue a Gibson endorsement. Through Scott's then-guitar tech, Mike Tempesta (who later went on to Powerman 5000 and Human Waste Project and who is now heading up artist relations at Yamaha), Scott learned about the defunct SH-TI pickup and he started playing them. So Scott plays both pickups and he refers to both as El Diablo.
Here's the SH-TI/El Diablo:
D.C. Resistance: 22.1 KOhms
Resonant Peak: 3.75 KHz
Magnet Type: Alnico 2 bar
Inductance: 7.9 Henry
The Duncan Designed HB-104 is a blade pickup that was used on a 5-string baritone instrument that Schecter made for -- you guessed it -- Mike Tempesta, back when he was a Schecter artist. The look was based on the SH-TI, but the sound is closer to an HB-103 (or SH-6b Duncan Distortion). In the Seymour Duncan pickup, the blades are the magnets (alnico). In the Duncan Designed pickup, the blades are steel and they connect with the ceramic magnet.
I can get you clips of the El Diablo if you'd like. The only obvious difference from the specs is that the RTM is Alnico 2 while th El is ceramic.
With that the diablo should be rougher sounding while the RTM would be expected to be warmer.
